1, wireless charger is good, convenient, safe and durable; The disadvantages are bondage, high price and low efficiency. Wireless chargerConvenient: Wireless charging belongs to one-to-many charging, which solves the problem that the interface is not applicable, and also avoids the phenomenon of poor contact caused by repeated plugging and unplugging of the mobile phone interface, which can better protect the mobile phone interface. 2, wireless charger is good, pros and cons are as follows: Advantages: In order to improve the unity of the mobile phone now most mobile phones are no longer with the headphone hole this design, but many users said that the headphone hole design is not humanized. But with the wireless charger, we can directly put the mobile phone on it, bring headphones to listen to music, but only limited to listening to music, want to play games that is not veryThe interface is not applicable, poor contact and other phenomena are avoided, and the elderly can also be easily used. (2) Versatility: a charger can charge multiple loads, and a family can buy a charger to meet the needs of the whole family.
2, benefits and convenience: wireless charging of mobile phones eliminates the trouble of using charging cables. Users only need to place the phone on the charging dock, without plugging or unplugging the charging cable, to start charging. This makes the charging process easier and faster. Flexibility: Wireless charging eliminates the need for a specific charging cable. Users no longer need to carry and connect specific types of charging cables that can be supported wirelesslyCharge on multiple charging stands at any time.
3, convenient: wireless charging belongs to one-to-many charging, which solves the problem that the interface is not applicable, and also avoids the phenomenon of poor contact caused by repeated plugging and unplugging of the mobile phone interface, which can better protect the mobile phone interface. Safety: With a variety of protection functions, such as: overcharge and overdischarge, metal foreign body detection and other functions, always protect the safety of users.
4, disadvantages: the charging speed is relatively slow. In the era of fast mobile phone charging, wireless charging is very slow. Now most of the wireless charging only support 5W charging, a little faster is only 5W. But notThe wire charge really doesn't quite meet our needs.
5, some Samsung mobile phones support wireless charging function, to achieve the function requires a separate charging kit, wireless charging and wired charging effect is the same, but the wireless charging time is relatively longer, no impact on the phone.
6, no harm to mobile phones. Wireless charger uses the latest wireless charging technology, by using the alternating magnetic field generated between the coils, the transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
Principle of wireless charging Wireless charging characteristics : electromagnetic induction. Charging base and mobile phone terminal respectively built-in wireless charging characteristics coil wireless charging characteristics , when the two near the wireless charging characteristics , The generator coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction Wireless charging characteristics , fromThe point energy is transferred from the originating end to the receiving end, and it begins to power the phone from the charging seat. Magnetic resonance.
The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger means noThe traditional charging power line is connected to the charger on the terminal device that needs to be charged, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electric energy, inductive coupling technology will become a bridge connecting the charging base station and the device.
Using the principle of electromagnetic induction charging equipment, its principle is similar to the transformer, through the transmitter and receiver end set coil, transmitter coil under the action of power to send electromagnetic signals, the receiving end coil receives electromagnetic signals and convert electromagnetic signals into current, so as to achieve the purpose of wireless charging.
If usedWireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, the device that needs to be charged can be charged by contacting the wireless charger after being energized.
Advantages of wireless charging: one: reduce loss. As we all know, when using wireless charging, you only need to connect the wireless charging board to the power supply, and then place the device that supports wireless charging on the wireless charging board. Although wireless charging still needs to be connected to the power supply, it can reduce the use of data lines and avoid large data linesQuantity loss and waste, relatively speaking, is a relatively environmentally friendly way to charge. Two: high adaptation rate.
Mobile phone wireless charging has the advantages of convenience, flexibility, and protection interface, and the disadvantages are low charging efficiency, slow charging speed, and high cost. Benefits Convenience: Wireless charging of mobile phones eliminates the hassle of using a charging cable. Users only need to place the phone on the charging dock, without plugging or unplugging the charging cable, to start charging. This makes the charging process easier and faster. Flexibility: Wireless charging eliminates the need for a specific charging cable.
The advantages of wireless charging are: reduce loss, high adaptation rate, and the disadvantages are: The distance is too small, only the transition technology; The benefits of wireless charging reduce the loss. As we all know, when using wireless charging, you only need to connect the wireless charging board to the power supply first, and then place the device that supports wireless charging on the wireless charging board.
The biggest advantage of wireless charging is convenience. Wireless charging has little impact on mobile phones, but when all electronic products support wireless charging, the convenience brought to users is more interesting. Apple said that future models of AirPods wireless headphones will use AirPower charging cases, soUsers simply place them on a charging pad to charge them.
